Congrats! That looks great! Take a look at my first post at the very bottom and you'll see a list of Mods that I have done to mine that might give you some ideas to do to yours. I got these Sequential Stealth turn signals for my XSE. They are totally black unlike others that still have a grayish lens these don't and they are super bright.
